Comparison of 2 electronic health record data extraction methods for laboratory tests used in the Veterans Aging Cohort Study Index.

ABSTRACT:

Objective

To compare Observational Medical Outcomes Partnership (OMOP) Logical Observation Identifiers Names and Codes (LOINC) and Veterans Aging Cohort Study (VACS) methods for extracting laboratory chemistry data from Veterans Health Administration (VA) electronic health records (EHR).

Materials and methods

Laboratory chemistry test results for 16 laboratory tests commonly assess in Veterans in VACS HIV (N = 143 830) followed in the VA 2015-2019 were extracted from the EHR and compared using 2 different data extraction approaches.

Results

The LOINC approach captured laboratory results from all 130 VA stations for all 16 labs. The VACS approach captured laboratory results from 128 to130 stations. Both approaches yielded laboratory results for a patient on a gi
